Method and apparatus for analyzing gas component derived from living body and disease determination supporting apparatus

Abstract

A method of analyzing a gas component derived from living body, includes: extracting a first gas component from a gas contained in an atmosphere by a first method and removing the extracted first gas component from the gas to defecate the atmosphere; obtaining a mixed gas of the defecated atmosphere and a second gas component from a subject; extracting the first gas component from the mixed gas by a second method; and analyzing the first gas component extracted from the mixed gas. The second method is the same as the first method.

1 . A method of analyzing a gas component derived from living body, the method comprising;
 extracting a first gas component from a gas contained in an atmosphere by a first method and removing the extracted first gas component from the gas to defecate the atmosphere;   obtaining a mixed gas of the defecated atmosphere and a second gas component from a subject;   extracting the first gas component from the mixed gas by a second method; and   analyzing the first gas component extracted from the mixed gas,   wherein the second method is the same as the first method.   
   
   
       2 . An apparatus for analyzing a gas component derived from living body, the apparatus comprising;
 a first trapping unit, which extracts a first gas component from a gas contained in an atmosphere by a first method, and removes the first gas component from the gas to defecate the atmosphere;   a mixing unit, which mixes the defecated atmosphere with a second gas component from a subject, to generate a mixed gas;   a second trapping unit, which extracts the first gas component from the mixed gas by a second method; and   a analyzing unit, which analyzes the first gas component extracted by the second trapping unit,   wherein the second method is the same as the first method.   
   
   
       3 . The apparatus according to  claim 2 , wherein
 the first trapping unit cools the gas contained in the atmosphere, which flows thereinto, to liquefy or solidify the gas, thereby extracting the first gas component, and   the second trapping unit cools the mixed gas, which flows thereinto, to liquefy or solidify the mixed gas, thereby extracting the first gas component.   
   
   
       4 . The apparatus according to  claim 2 , wherein each of the first and second trapping units is provided with a material which sorbs the first gas component. 
   
   
       5 . The apparatus according to  claim 2 , wherein the mixing unit generates the mixed gas by allowing the subject to breathe the atmosphere defecated by the first trapping unit. 
   
   
       6 . The apparatus according to  claim 2 , wherein the mixing unit generates the mixed gas by exposing a product substance of the subject or a part of the subject to the atmosphere defecated by the first trapping unit. 
   
   
       7 . The apparatus according to  claim 2 , wherein the first trapping unit includes a function which is obtained by connecting a plurality of the second trapping unit to one another. 
   
   
       8 . A disease determination supporting apparatus comprising:
 the apparatus according to  claim 2 ; and   a unit, which supports determination of a possibility of disease of the subject depending on a component and concentration of the analyzed first gas component.
